Tonsillitis is inflammation of the tonsils most commonly caused by viral or bacterial infection. Symptoms may include sore throat and fever. When caused by a bacterium belonging to the group A streptococcus, it is typically referred to as strep throat. The overwhelming majority of people recover completely, with or without medication. In 40% of the cases, symptoms will resolve in three days, and within one week in 85% of people, regardless of whether streptococcal infection is present or not.
A timer switch is a timer that operates an electric switch controlled by the timing mechanism. The switch may be connected to a circuit operating from mains power, or for lower-voltage circuits, including battery-operated equipment in vehicles. It may be built into power circuits, plugged into a power point with equipment plugged into the timer instead of directly into the power point, or built into equipment as, for example, a sleep timer that turns off a television receiver after an interval. The mechanism may be mechanical , electromechanical (a slowly rotating geared motor that mechanically operates switches) or electronic, with semiconductor timing circuitry and switching devices and no moving parts.
Sensodyne is a brand of toothpaste that was first sold by Block Drug, a Brooklyn, New York-based company established in 1907 by pharmacist, Alexander Block. The toothpaste was first marketed in 1961 as a desensitising toothpaste based on a strontium chloride formulation. In 1980, Sensodyne launched a new toothpaste containing potassium nitrate, a mild local sedative. In 2000 Block Drug was purchased by GlaxoSmithKline, and in 2006, Sensodyne Pronamel was released and is marketed as a toothpaste that protects against the effects of dental erosion.
Oh, and people in the firearms world seem to be breathing a little easier now that the Republicans have control over both champbers of Congress, so now you can pick up 1,000 rounds of 55gf FJM 5.56 rounds -- and we're talking reloadable brass cases here too, none of this steel shit -- for $274, and that includes a US issue .50cal ammo can. That was unheads of just a few short months ago.
Hi Ernie, saw the night video of a Harrier landing on deck and have to wonder how do they avoid scorching the deck, or is that just part of the cost of doing business? I never thought about it until I saw the night video. The conical exhausts are much easier to see that way. It would probably not be a good idea to step on those spots for a while or drive the plane's wheels over the hot spot, esp. if the deck is steel. Seawater is free. Would flooding the deck before landing make it unsafe to land? VTOL doesn't look all that safe anyway. Anything loose undeneath will get bounced and thrown up into the air. At least with normal straight takeoff and landing you should be able to stand to on side or the other and be in the clear. There isn't any clear zone around a Harrier taking off or landing vertical. Just the downwash would be enough to throw someone off the deck. Of course the Brits are a bit braver than I just for venturing into the North Sea. It isn't shallow, warm and calm like the Gulf of Mexico. David
An interesting question, David. One which I will try to answer for you. But before I try, let me begin by openly declaring I am henceforth talking with a paper asshole. That being said, here's what I believe happens and I'm sure if my assumptions are incorrect, more than one person will step in to correct me.
Doing some research on the Rollys-Royce Pegasus -- the jet which powers the Harrier -- I found two things worth mentioning. The first, the uncooled temperature of the jet exhaust is around 650C, or 1200F to us 'Muricans. The second, there is a water injection system which can (indirectly) help control the temperature of the jet's exhaust, although this is primarily used on takeoff as opposed to landing. Also consider the Harrier has four vectoring exhaust ports, so that's going to disperse the intense heat generated by the engine, at least when compared to single vectoring nozzle like on the new F-35. I also performed several searches trying to find the thickness of the aircraft carrier deck, but came up empty (and I'm not being watched by the NSA). Either way, compare this relatively low engine exhaust temperature to the melting point of steel (2600-2800) and I doubt any deck scorching can occur. And although special caution is urged for flight operations around VTOL aircraft (CTRL-F and find HARRIER), I also couldn't find anything about special footwear worn by aircraft handlers -- those are the dudes in yellow who tend to be the first people to approach a recently landed Harrier, I would have to imagine if a jet idles with its nozzles pointed down for more than a certain amount of time, certain precuations are in place to prevent any mishaps. [regular takeoff/landing | no nose gear landing] And those are all of genuine Harrier footage, too. No green screen special effects there.
Now, compare the Harrier's 1200F degree exhaust being dispersed among four nozzles all several feet apart, to the single nozzle of the F-35's 1700F degree exhaust and I bet that's going to come into play on steel decks, but certainly will in regards to conventional runways. You can see the F-35's first arrested landing here.
